  2. Thomson problem - Wikipedia

    en.wikipedia.org/wiki/Thomson_problem

    The Thomson problem also plays a role in the study of other physical models including multi-electron bubbles and the surface ordering of liquid metal drops confined in Paul traps. The generalized Thomson problem arises, for example, in determining arrangements of protein subunits that comprise the shells of spherical viruses. The "particles" in ...

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.

  4. Visibility (geometry) - Wikipedia

    en.wikipedia.org/wiki/Visibility_(geometry)

    In geometry, visibility is a mathematical abstraction of the real-life notion of visibility. Given a set of obstacles in the Euclidean space , two points in the space are said to be visible to each other, if the line segment that joins them does not intersect any obstacles.

  7. Regular icosahedron - Wikipedia

    en.wikipedia.org/wiki/Regular_icosahedron

    In the Thomson problem, concerning the minimum-energy configuration of charged particles on a sphere, and for the Tammes problem of constructing a spherical code maximizing the smallest distance among the points, the minimum solution known for = places the points at the vertices of a regular icosahedron, inscribed in a sphere. This ...

  8. Talk:Thomson problem - Wikipedia

    en.wikipedia.org/wiki/Talk:Thomson_problem

    I think the claim on this page, that J.J. Thomson posed this problem in 1904 as part of his proposal for an atomic model, is NOT true. I know that several papers cite the 1904 paper as a reference for background information on the Thomson Problem. However, I don't think this specific mathematical problem is described in the 1904 paper.

  9. Art gallery problem - Wikipedia

    en.wikipedia.org/wiki/Art_gallery_problem

    In decision problem versions of the art gallery problem, one is given as input both a polygon and a number k, and must determine whether the polygon can be guarded with k or fewer guards. This problem is -complete, as is the version where the guards are restricted to the edges of the polygon. [10]
